Abstract
The utility model is mainly used in gasing pump in unexpected shutdown situation to the rapid pressure release of output terminal air pressure; in particular to the passive pressure relief device of a kind of beam tube gasing pump; comprise valve body; valve body one end arranges suction port; the other end arranges air vent; top arranges the air outlet all communicated with suction port and air vent; between suction port and air vent, leather cup is set; between leather cup and air vent, regulating spool is set; regulating spool laterally runs through air vent and arranges; arrange spring between air vent and leather cup, regulating spool afterbody arranges pressure release micropore, and pressure release micropore communicates with air vent.Pressure relief device is work in the passive state completely, can meet beam tube gasing pump meet accident shut down time, can pressure release smoothly, create conditions for beam tube gasing pump normally recovers startup.
Description
Technical field
The utility model relates to the passive pressure relief device of a kind of beam tube gasing pump, is mainly used in gasing pump in unexpected shutdown situation to the rapid pressure release of output terminal air pressure.
Background technique
At present, in coal in China, mine industry, beam tube gasing pump starts to be promoted use in positive pressure bundle pipe monitoring system, due to the restriction of inflammable and explosive working environment, makes must meet requirement of explosion proof at the equipment of this environmental work.In gasing pump application, require it is all generally adopt to have the pressure relief device of Power supply to realize to the startup pressure release of gasing pump, this causes obstacle to such air pump in the use of inflammable and explosive environment.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of timely pressure release realizing the pressurized gas when beam tube gasing pump is shut down, the passive pressure relief device of beam tube gasing pump started smoothly with the safety reached when restarting beam tube gasing pump.
The passive pressure relief device of beam tube gasing pump described in the utility model, comprise valve body, valve body one end arranges suction port, and the other end arranges air vent, and top arranges the air outlet all communicated with suction port and air vent, between suction port and air vent, leather cup is set, arrange regulating spool between leather cup and air vent, regulating spool laterally runs through air vent and arranges, and arranges spring between air vent and leather cup, regulating spool afterbody arranges pressure release micropore, and pressure release micropore communicates with air vent.
This device is arranged in beam tube gasing pump output pipe, under working condition, any impact can not be produced to the flow of beam tube gasing pump, pressure, during beam tube gasing pump normal working, gas after the compression of beam tube gasing pump enters the suction port of the passive pressure relief device of beam tube gasing pump, under the effect of gas pressure, elastic cup is moved to the left, pressure release micropore is tightly closed, elastic cup periphery shrinks and produces gap with valve interior wall simultaneously, and gas enters air delivering pipeline through elastic cup periphery through air outlet smoothly.When beam tube gasing pump is shut down; suction port inputs without pressurized gas; elastic cup in suction port loses pressure; under the action of the spring, elastic cup moves to right, thus leaves pressure release micropore; now; air vent is communicated with air outlet by pressure release micropore, and the gas of air outlet is released in air through pressure release micropore by air vent, realizes passive pressure release.
Described regulating spool is set to hollow-core construction, and hollow regulating spool is coaxial with pressure release micropore, and leather cup is elastic cup, and one end that leather cup is connected with spring arranges projection.Projection can play guiding and supporting effect to spring.
The beneficial effects of the utility model are:
Pressure relief device is work in the passive state completely, can meet beam tube gasing pump meet accident shut down time, can pressure release smoothly, create conditions for beam tube gasing pump normally recovers startup.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, air outlet 2, valve body 3, suction port 4, leather cup 5, pressure release micropore 6, spring 7, regulating spool 8, air vent 9, projection.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the passive pressure relief device of beam tube gasing pump described in the utility model, comprise valve body 2, valve body 2 one end arranges suction port 3, the other end arranges air vent 8, top arranges the air outlet 1 all communicated with suction port 3 and air vent 8, leather cup 4 is set between suction port 3 and air vent 8, regulating spool 7 is set between leather cup 4 and air vent 8, regulating spool 7 laterally runs through air vent 8 and arranges, arrange spring 6 between air vent 8 and leather cup 4, regulating spool 7 afterbody arranges pressure release micropore 5, and pressure release micropore 5 communicates with air vent 8.Regulating spool 7 is set to hollow-core construction, and hollow regulating spool 7 is coaxial with pressure release micropore 5, and leather cup 4 is elastic cup, and one end that leather cup 4 is connected with spring 6 arranges protruding 9.
During working state, beam tube gasing pump gas is after compression inputted by the suction port 3 of the passive pressure relief device of beam tube gasing pump, and under the promotion of pressurized gas, elastic cup 4 moves to left, and is closed by pressure release micropore 5.The output gas of gasing pump enters air outlet 1 through the periphery of elastic cup 4, and now, the right atrial pressure of elastic cup 4 is slightly larger than air outlet 1 pressure, and pressure release micropore 5 is tightly closed by leather cup 4.When gasing pump is shut down suddenly, elastic cup 4 loses driving pressure, and now elastic cup 4 pressure at two ends tends to be balanced rapidly.Because the diameter of pressure release micropore 5 is very little, the pressure reduction impact of its area on leather cup 4 two ends is very faint, under the active force of spring 6, on the left of leather cup 4, total pressure is greater than right atrial pressure, and therefore, leather cup 4 is pushed to and moves to right, pressure release micropore 5 is opened, the gas of air outlet 1 end is released away.When beam tube gasing pump starts again, because air outlet 1 end gas pressure is identical with barometric pressure, therefore, beam tube gasing pump can start smoothly under non-loaded state.
